WIRE-BARBING MACHINE.

SPECIFICATION forming part of Letters Patent No. 318,821, dated May 26,1885.

Application filed April 2?, 1883.

i0 @ZZ whom it Ti l/(by concern.-

Be it known that I, DANIEL C. STOVER, a resident of Frceport, in thecounty ofStephenson and State of Illinois, have invented certain new anduseful Improvements in Vire- Barbing Machines and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same.

My invention is an improved machine for applying to two-strandfence-cables certain forms of barbs whose completion requires theformation of a bend or shoulder in one of the ends of the barb and thetucking between the cable-strands of the end so shouldered. The detailsof the machine are fully described and its operation explained in thefollowing speci licatiomand shown in the accompanying drawings, inwhich- Figure l is a plan of the entire machine; Fig. 2, a frontelevation of the same; Fig. 3, a side elevation of the bearings andgearing of the barbing spindle and sleeve, and Figs. 4, 5, 6, 7, and 8perspective views showing the position of the barbforming parts in thesuccessive steps of the formation of a barb.

In these views,A is the bed of the machine; 13, the driving-shaft, and Ba side shaft at right angles to the driving-shaft,to which it isconnected by bevel-gears. On the shaft B are rigidly mounted threecams,0 G C, the first of which, 0, imparts reciprocal rotary motion in avertical plane to the segmental gear I-I, while the second cam, C,imparts longitudinal reciprocal motion to a bar, D,which slides inbearings E, and is provided at its inner end with an anvil, R, formedintegrally with it, and the third cam, 0, produces reciprocal rotarymotion in a horizontal plane of the segmental gear H. The pivots aboutwhich the segments H H rotate, and the bearings in which the pivots arejournaled, are evident from the drawings. The cams G O actuate thesegment H and bar D, respectively, by means of pins or rollers attachedto the lever .D and bar D, which pins work in grooves in the side facesof the cams, while the cam C" actuates the segment H by means of a pinor roller in the lever D",nioving in the groove in the periphery of thecam.

(N0 model.)

Near the center of the bed,and parallel with the shaft B, stand twoposts, F F, in which is journaled, near the surface of the bed, a horizontal shaft, B, on which is rigidly mounted, in the space between theposts, a pinion, G, which engages with the segmental gear H. On the sameshaft, B, is rigidly mounted, in front of the post F, a larger pinion,G, and immediately above the pinion G is a small pinion, G, whichengages with it. The pinion G is mounted on a horizontal spindle, l andis formed integrally with asleeve,L, which surrounds and turns freelyupon the spindle. The spindle P is formed integrally with the post orrigidly attached to it, and the post and spindle are longitudinallyperforated for the passage of the two main wires to be barbed. The frontfaces of the sleeve and spindle are flush, and the sleeve is providedwith an ordinary wrapping-lug, 0.

Between the perforations in the spindle is a diametrical slot, Q, of awidth equal to the diameter of the barb-wire, and a depth suffi cient topermit the tucking through it of one of the ends of the barb, ashereinafter set forth. The sleeve is also slotted at Q.

Above and in front of the sleeve and spindle is a vertical bearing, Z,supported by a suit able post or support, K, and in this bearing rotatesfreely a spindle, which carries at its upper end a rigidly-mountedpinion, G, engaging with the segmental gear H.

To the lower end of the vertical spindle is rigidly attached a verticalrod, S, which carries an integrally-formed curved horizontal finger, T,which lies in the plane of theslot Q. in the horizontal spindle P.

At the side of the sleeve and spindle is the horizontal bar D, whosereciprocal motion has already been described. The inner end of the baris provided with an anvil, R,whose upper surface is practically in thesame plane as the lower face of the slot Q, while its front face isslightly in front of the front face of the sleeve and spindle. is toassist in forming a bend or shoulder in one of the ends of the barbpreparatory to tucking the same through the slot Q, as hereinafterexplained, and its reciprocal motion is imparted to it for the purposeof permitting the partial wrapping of the barb while the an- The officeof this anvilvil is withdrawn from the spindle, and afterward completingthe wrap with the anvil in such position that the end of the barb-muststrike and rest upon it. As shown, the bar and anvil are bent verticallyand laterally to bring the faces of the anvil to the required positionswithout interfering with the other working parts of the machine; but itis evident that the form of these members is accidental, and may bevaried to suit different machines, or even in the same machine.

It is evident from the drawings and the foregoing description that therotation of the shaft 13, with its earns O O G, will impart rcciprocalrotary motion to the sleeve L, reciprocal longitudinal motion to the barD and anvil R, and reciprocal rotary motion to the vertical spindlewhich carries the rod S, and that the rotation of the vertical spindlewill carry the finger T through the slot Q. It is equally plain that thecams may be so timed as to perform these operations in any desiredorder.

The operation of the barb-forming parts in the wrapping of a barb is asfollows: The sleeve and spindle being in the position shown in Fig. 4,with the slots Q Q, the former in the sleeve and the latter in thespindle, being in the same plane, the barb-wire N is fed forward bysuitable means, passing between the main wires M and under thewrappingpin O. The sleeve L is then rotated in the direction indicatedby the arrow in Fig. 4 through an angular space of about two hundred andseventy degrees to the position shown in Fig. 5, when the anvilR isthrust forward to a position almost in contact with the sleeve. Therotation of the sleeve is then continued in the same direction until ithas completed an entire revolution of three hundred and sixty degrees,when it reaches the position shown in Fig. 6, forming a bend in thebarb-wire near the main wires, and bringing the free portion of thebarb-wire into contact with the upper surface of the anvil It and intothe plane of the slots Q Q. In Fig. 7 the sleeve and spindle are in theposition shown in Fig. 6; but the vertical rod S and finger T are shownin position to tuck the free end of the barb through the slot. From theposition shown in Fig. 7 the rod S is rotated one hundred and eightydegrees in the direction indicated by the arrow. The finger T is carriedthrough the slot and thrusts the end of the barb through before it tothe position shown in Fig. 8. The barb is then severed by suitable meansbetween the feed-rolls and the main wire, and the ends N N are wrappedin opposite directions by any suitable device. The end N may be carriedeither upward or downward into a vertical plane, the end N being, ofcourse, carried in the opposite direction in either case, so that twodistinct forms of barbs.

may be made from the blank shown in Fig. 8. I havefound it best inpractice to provide the anvil R with means substantially as shown formoving it in and out with relation to the sleeve and spindle; but if itbe so formed as to project in front of the face of the sleeve a distanceequal to the diameter of the barb-wire it may be stationary, and stillpermit the wrapping of the barb shown in these drawings. It is plainthat if so formed the barb-wire, when fed forward to the position shownin Fig. 4, would lie wholly in front of the face of the anvil, and thefirst half of the wrap could be made without hinderance from theanvil,whi1e the end of the barb during the last half of the wrap wouldlie above the end of the anvil, and would strike on its upper surface,as shown. There are, however, many barbs which cannot be formed withoutthe use of a movable anvil, and I have therefore shown and described itas movable.

I am aware that the combination of a slotted sleeve and spindle withmeans adapted to tuck the end of a barb through the same is not new,thatmechanism having been invented by Frank \V. Brainerd, and beingfully shown and described in Letters Patent No. 277,451, issued to saidBrainerd May 15, 1883. Neither do I claim any novelty for the devicesused to actuate the barb-forming parts of this machine, as the cams andsegments shown are well-known devices in wire-barbing machinery.

In a pending application of my own filed August 9, 1883, and having theSerial No. 103,223, I have shown and described a tucking-finger adaptedto pass between the main wires and to tuck between said wires the end ofa barb-wire. In the mechanism shown and described in said applicationNo. 103,223, however, the finger is so arranged as to retate forwardinstead of backward, as in the machine shown herein, and the point ofthe finger, instead of passing through a slot in the spindle, passesacross and in front of the face of the spindle.

Having, however, described my invention and explained its operation,what I claim as new, and desire to secure by Letters Patent,

1. In a wire-barbing machine, the combina tion of means for supportingthe main wires to be barbed, means for wrapping the barb about said mainwires, an anvil adapted to form a bend or shoulder in one of the ends ofsaid barb, substantially as shown, and means for tucking such shoulderedend between the main wires, substantially as shown and described, andfor the purpose set forth.
